Hybrid Emergency Room Systems (HERS) have emerged as a promising solution to address the challenges of timely and effective trauma management and acute care interventions. This review provides an in-depth exploration of HERS, its definition, historical development, advantages, disadvantages, successful implementations, economic considerations, and its potential role in the future of emergency care. HERS is designed to facilitate rapid assessment, diagnosis, and interventions by integrating various medical specialties, advanced imaging technologies, and interventional capabilities within the emergency care environment. Through comprehensive literature review and case studies, this article demonstrates how HERS has been utilized to improve patient outcomes in cases of trauma, cardiovascular emergencies, and other critical conditions. The advantages of HERS include enhanced coordination among medical specialties, streamlined communication, real-time imaging capabilities, and optimized resource utilization. However, challenges such as high costs, complexity, and accessibility limitations need to be considered. This review also discusses the economic implications of implementing HERS and presents a model-based cost-benefit analysis, underscores the importance of carefully planning and evaluating the implementation of HERS, considering its potential benefits and challenges. As HERS continues to evolve and gain recognition globally, its role in modern healthcare and emergency services is poised to become increasingly significant.
